Oracle Linux: CVE-2024-41035: ELSA-2024-12610: Unbreakable Enterprise kernel security update (IMPORTANT) (Multiple Advisories)

In the Linux kernel, the following vulnerability has been resolved:
USB: core: Fix duplicate endpoint bug by clearing reserved bits in the descriptor
Syzbot has identified a bug in usbcore (see the Closes: tag below)
caused by our assumption that the reserved bits in an endpoint
descriptor's bEndpointAddress field will always be 0. As a result of
the bug, the endpoint_is_duplicate() routine in config.c (and possibly
other routines as well) may believe that two descriptors are for
distinct endpoints, even though they have the same direction and
endpoint number. This can lead to confusion, including the bug
identified by syzbot (two descriptors with matching endpoint numbers
and directions, where one was interrupt and the other was bulk).
To fix the bug, we will clear the reserved bits in bEndpointAddress
when we parse the descriptor. (Note that both the USB-2.0 and USB-3.1
specs say these bits are "Reserved, reset to zero".) This requires us
to make a copy of the descriptor earlier in usb_parse_endpoint() and
use the copy instead of the original when checking for duplicates.
A vulnerability was found in the usb_parse_endpoint() function in the Linux kernel's usb drivers, where improper handling of the reserved bits in an endpoint descriptor's bEndpointAddress field can lead to confusion in the endpoint_is_duplicate() routine in config.c. This will erroneously treat the same endpoint descriptors as distinct, given that the reserved bits are not properly cleared. This can potentially lead to unexpected behavior from connected USB devices.
